FIELD: teaching.
SUBSTANCE: fixator includes lever on instrument body with the possibility to change strings tension to execute tremolo. One of lever arms is installed with the possibility of interaction with one end of axis spring-loaded in longitudinal direction, having two pre-stressed springs. Springs execute both working and mount functions. Fixator has circular clamp, where axis enters, having possibility to move inside circular clamp with loosened screw of circular clamp or is located as fixed relative to circular clamp with tightened screw of circular clamp. Cartridge, inside of which previously compressed spring is located, resting with one end against cartridge bottom, and with another end - against stem, is fixed to body of string instrument with the help of screw. Stem under action of this spring rests against nut screwed into the other end of cartridge, having hole, where stem tail exits, being connected by circular clamp with thrust. Previously stretched spring is placed onto thrust, being fixed with one end to ends of axis passing through thrust. With its other end previously stretched spring is fixed into hole of tremolo mechanism lever. At the same time previously stretched string performs role of thrust guide, which rests against lever of tremolo mechanism.
EFFECT: guaranteed return of tremolo mechanism into initial position with ideal accuracy, which makes it possible to preserve tuning system of musical instrument.
